When to prune potted wisteria

The pruning time for wisteria bonsai is usually before budding in early spring, after flowering and when the leaves fall, and the corresponding seasons are spring, summer and winter.

Spring pruning is to prune diseased branches, dead branches and overlapping branches. It is best to combine it with repotting and root pruning. Summer pruning is to prune overly long branches, and cut new branches back 15 cm. In winter, after the leaves fall, the skeleton can be seen more clearly, so some unnecessary branches can be cut off.

Tips for pruning potted wisteria

1. Pruning and shaping: Pruning and tidying are the main steps, and tying is secondary. The purpose of this is to fully express the simple and beautiful natural form of the plant. When pruning, the branches should be staggered to avoid monotony, but there should not be too many layers. We often see various forms of wisteria bonsai, and you can use your imagination to make a beautiful shape.

2. Prune branches and leaves: Prune the withered branches and leaves so that the potted wisteria can grow better. If you find insect pests, you must prune them in place, especially if there are insect pests on the branches, then you have to prune them. If the temperature is low after pruning, you should keep it indoors or cover it for insulation, so that you can keep the pruned potted wisteria well.

3. Pruning makes it grow faster: When wisteria sprouts new buds in spring, you should remove the dense buds appropriately. When the new branches grow to more than 20 cm, you can cut off the overly long branches. September is the period when the old leaves of wisteria tend to age and droop. Because it will affect the appearance, you can remove the old leaves to speed up the sprouting of new leaves. The sprouting new leaves are relatively tender, which can effectively delay the fall period and extend the viewing period of the bonsai.

4. Pruning for flowering : In summer, the long branches grown that year should be shortened to 15 cm after the flowers have faded, and unnecessary branches and dead branches should be cut off; in winter, the long branches pruned in summer should be shortened to 3 to 5 buds; before flowering in early spring, the useless branches and buds on the main trunk should be cut off to promote the growth of flower branches; the main trunk should not be too long, and a maximum of 5 main branches should be left in different directions of the stem.

Precautions for pruning potted wisteria

In early spring, before flowering, the useless branches of the main trunk should be cut off to promote the growth of flower branches. The main trunk should not be too long, and there should be no more than 5 main branches in different directions of the stem. The side branches should be shorter than the main branches. The new branches that grow every year should be properly pruned, the weak ones should be removed and the strong ones should be kept, and the tops should be appropriately pinched to try to maintain the shape of the pot plant and the beauty of the flowering.
